Study on the Chemical Constituents of Essential Oils of Two Annonaceae Plants from Vietnam: Miliusa sinensis and Artabotrys taynguyenensis

Abstract

The compositions of essential oils obtained by hydrodistillation of two Annonaceae plants from Vietnam were reported. The essential oils were analysed for their constituents by means of gas chromatographyflame ionization detector (GC-FID) and gas chromatography-mass spectrometry techniques (GC-MS). The principal components of the leaf of Miliusa sinensis Fin. & Gagnep were -caryophyllene (19.5%), δselinene (10.3%), caryophyllene oxide (10.1%) -humulene (7.9%) and -elemene (7.1%). The major compounds identified in the leaf oil of Artabotrys taynguyenensis Ban were valencene (40.1%) along with δ-selinene (8.8%), α-pinene (6.7%), α-muurolene (5.1%) and α-panasinsene (5.1%). However, bicycloelemene (25.1%), bicyclogermacrene (23.7%) and spathulenol (12.8%) were the principal compounds in the stem oil. This is the first report on the volatile constituents of these plant samples.
